OxiZ 0.2.2 Released — Real CDCL Internals, Deeper Z3 Compatibility, ML-Guided Branching

OxiZ is a pure-Rust SMT solver reimplementing Z3. 0.2.2 ships real LBD clause scoring (replacing the old stub), Big-M primal simplex for LP, an LRU lemma cache, ML conflict-hook branching, and deeper Z3-compat APIs — all with 100% Z3 parity and zero C/C++/Fortran.

OxiZ 0.1.0 Released — A Pure Rust SMT Solver, the First Step Toward Replacing Z3

OxiZ is a Pure Rust Satisfiability Modulo Theories solver reimplementing Z3 — a full CDCL(T) architecture with EUF/LRA/LIA/BV/Arrays/Strings/FP/Datatypes theories, SMT-LIB2 support, and roughly 90% Z3 feature parity, all with zero C/C++. This is its first public release.
